CAR-SILL.

SPECIFICATION forming part of Letters Patent No. 762,796, dated June 14, 1904. A Application filed Novemb r 4, 1901. Serial No. 81,007- (No model.) I

To a. whom it mal concern:

Be it known that I, ARTHUR B. BELLOWS, of Pittsburg, Allegheny county, Pennsylvania, have invented a new and useful Car-Sill, of

which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of, this specification, inwhich Figure l is a side elevation of a car-sill con 1 structed in accordance with my invention. Fig. 2 is a cross-section showing the center and side sills of a car provided with my improved strengthening members. Fig. 3 is a detail side elevation, on a larger scale, showing the method of securing the strengthening members. Fig. 4 is a cross-section of the center sill of Fig. 3. Figs. 5 to 10, inclusive, are similar cross-sections showing modified forms; and Figs. 11 and 12 are detail views showing the preferred form of sill construction at the bolster.

My invention relates to the longitudinal sills employed in railway-cars, and is designed to provide a simple, cheap, and eflicient con- 5 struction which will take the place of the fishbelly form of sill now commonly employed and will enable commercial rolled shapes to be .usedand decrease the depth of the sill over the trucks.

3 Heretofore in order to obtain the necessary strength at the central portion of car-sills the webs of these sills have been commonly formed of gradually-increasing depth from the ends toward the center. The making of these sills,

whether formed of pressed steel shapes or of member 5 is composed of a platelO, with an ordinary angle 11 secured along its lower edge with the flange turned outwardly. In

a sheet with angles riveted along its edges, has been an expensive operation and necessitated the use of special and expensive machinery. My invention obviates this difliculty; and it 4 consists in securing along the central part of the sill a separate longitudinal strengthening member, this member adding the necessary strength at the desired points.

The invention further consists in securing a strengthening member along the central part of the sill, this strengthening member having a vertical web, and, further, in using rolled shapes for both the sill and the strengthening member and in the special construction 5 and arrangementof the parts, s, hereinafter more fully described, and set forth in ,the claims.

In the drawings, referring to Figs. 1 to 4, inclusive, in which I show a preferred form of my invention, 2 2 represent a pair of com 5 5:

mercial rolled channels forming a center sill and having their flanges 3 turned outwardly. Along the central part of the length of each of these channels I rivet to the inner face of the web the longer leg 4 of a commercial 6o.

angle, the flange 5 of which extends horizontally. and is substantially parallel with the flange of the channel throughout the major portion of its length. At each end the strengthening-angle is preferably bent upwardly, as shown at .6, the flanges being cut away from the end portions to allow the web to lie in this form. The angle and channel may be secured together by rivets 7 or in any other desirable manner. If side sills are 7 used, asingle channel 8 may be employed, with a strengthening-angle 9 secured thereto in the same manner as in the case of the center sill, the side sill thus being similar to one-half of the center sill, as shown in Fig. 2. The

turning up of the ends of the strengthening members may be used or not, as desired. In the form of Fig. 5 I show a construction similar to that of Fig. 4, except that the flanges 5 of the strenghening-angles are turned in- 80.

wardly toward each other. In this form the ends of the strengthening members can of course be bent upwardly without the cutting.

away of the flanges. v

In the form'of Fig. 6 each strengthening 8 5 the form of Fig. 7 the construction is the same as that of Fig. 6, plates 10 being used with angles 11, the flanges of the angles being turned inwardly,'however, and extendingtoward each other.

In Fig. 8 I show the strengthening members as consisting of small channels having their upper flanges 12 secured directly to the lower flanges of the sill-channels.

InFig. 9 I show the strengthening members as consisting of channels placed inside- .the sill-channels, withtheir webs rivetedto- '1 gether, the flanges 12 of the strengtheningchannels projecting inwardly toward each other. Y

In the form of Fig. 10 the strengthening members do not extend beneath the sill, but are in the form of simple angles riveted to the inner faces of the channels, with their flanges 11" extending inwardly toward each other on the same plane as the lower channelflanges. I

In all the forms shown the ends of the strengthening members maybe and preferably are bent upwardly, except in the form of Fig. 8, where end web-plates may be used for securing the strengthening members to the sill.

In order to decrease the depth of the rolled section over the bolster, I'preferably use, in connection with the additional strengthening member above described, a construction such, for example, as shown in Figs. 11 and 12 that is, I cut away the lower portions of the channels or other rolled shapes forming the center sill, as shown at 13, at points over the bolsters. I am thus enabled to use a deep channel or other shape, while at the same time the car-body is not raised unduly and a strong construction is aflorded. In the form shown the lower flanges and part of the webs are cut away, strengthening-angles 14 are secured in pairs to the outer bases of the webs of the channels, and the center plate 15 is secured to an intermediate plate 16, fastened to the angles 14 and also to the angle-pieces 17 of the built-up bolster. This bolster, however, may be of any desired form, and its connection to the sill may be varied widely.

The advantages of my invention result from the simplicity and cheapness of construction of the sill. The sill and its strengthening member may be and preferably are formed of commercial rolled shapes, and where heretofore if a rolled shape were used for the sill the depth of sill over the trucks must be excessive. By the use of the added strengthening member along the central part I reduce the depth of the sill over the trucks, and thus decrease weight and also lower the car-body. By cutting away the center sill over the bolsters I increase the strength without elevating the car-body.

Many variations may be made in the construction and shape of the sill and its strengthening member or members without departing from my invention.

I claim 1. A longitudinal car-sill consisting of a girder having avertical web with flanges along its upper and lower edges,and a strengthening member of less length consisting of a rolled flanged shape, said strengthening member being secured at the intermediate parts of the sill member and below its top; substantially as described.
